fuse: auxiliary gfid mount support

2013-07-19T08:14:08+00:00

* files can be accessed directly through their gfid and not just
  through their paths. For eg., if the gfid of a file is
  f3142503-c75e-45b1-b92a-463cf4c01f99, that file can be accessed
  using /.gfid/f3142503-c75e-45b1-b92a-463cf4c01f99

  .gfid is a virtual directory used to seperate out the namespace
  for accessing files through gfid. This way, we do not conflict with
  filenames which can be qualified as uuids.

* A new file/directory/symlink can be created with a pre-specified
  gfid. A setxattr done on parent directory with fuse_auxgfid_newfile_args_t
  initialized with appropriate fields as value to key "glusterfs.gfid.newfile"
  results in the entry /bname whose gfid is set to args.gfid. The
  contents of the structure should be in network byte order.

  struct auxfuse_symlink_in {
        char     linkpath[]; /* linkpath is a null terminated string */
  } __attribute__ ((__packed__));

  struct auxfuse_mknod_in {
        unsigned int   mode;
        unsigned int   rdev;
        unsigned int   umask;
  } __attribute__ ((__packed__));

  struct auxfuse_mkdir_in {
        unsigned int   mode;
        unsigned int   umask;
  } __attribute__ ((__packed__));

  typedef struct {
        unsigned int  uid;
        unsigned int  gid;
        char          gfid[UUID_CANONICAL_FORM_LEN + 1]; /* a null terminated gfid string
                                                      * in canonical form.
                                                      */
        unsigned int  st_mode;
        char          bname[];     /* bname is a null terminated string */

        union {
                struct auxfuse_mkdir_in   mkdir;
                struct auxfuse_mknod_in   mknod;
                struct auxfuse_symlink_in symlink;
        } __attribute__ ((__packed__)) args;
  } __attribute__ ((__packed__)) fuse_auxgfid_newfile_args_t;

  An initial consumer of this feature would be geo-replication to
  create files on slave mount with same gfids as that on master.
  It will also help gsyncd to access files directly through their
  gfids. gsyncd in its newer version will be consuming a changelog
  (of master) containing operations on gfids and sync corresponding
  files to slave.

* Also, bring in support to heal gfids with a specific value.
  fuse-bridge sends across a gfid during a lookup, which storage
  translators assign to an inode (file/directory etc) if there is
  no gfid associated it. This patch brings in support
  to specify that gfid value from an application, instead of relying
  on random gfid generated by fuse-bridge.

  gfids can be healed through setxattr interface. setxattr should be
  done on parent directory. The key used is "glusterfs.gfid.heal"
  and the value should be the following structure whose contents
  should be in network byte order.

  typedef struct {
        char      gfid[UUID_CANONICAL_FORM_LEN + 1]; /* a null terminated gfid
                                                      * string in canonical form
                                                      */
        char      bname[]; /* a null terminated basename */
  } __attribute__((__packed__)) fuse_auxgfid_heal_args_t;

  This feature can be used for upgrading older geo-rep setups where gfids
  of files are different on master and slave to newer setups where they
  should be same. One can delete gfids on slave using setxattr -x and
  .glusterfs and issue stat on all the files with gfids from master.

Thanks to "Amar Tumballi"  and "Csaba Henk"
 for their inputs.

mount/fuse: Provide option to use/not use kernel-readdirp

2013-07-12T14:36:05+00:00

By default fuse kernel readdirp usage in fuse xlator is off.
When mount option use-readdirp=yes is provided it starts using
fuse-kernel's readdirp.

glusterfsd: Remove 'top {read,write}-perf' thread

2013-02-15T07:25:39+00:00

'volume top {read,write}-perf' were performed in a different thread on the brick
process, to prevent them from blocking the main polling thread. This was
essential earlier when the rpc actor functions were run in the epoll thread. Now
rpc actors can be launched on their own threads with the introduction of
synctask support for rpcsvc. The brick-op actors are now launched using this
feature, which makes the need for '{read,write}-perf' to be performed in a new
thread.

fuse-bridge: Pass unknown option down to fuse

2012-09-12T21:39:06+00:00

In Linux, certain "filesystem-specific" options (passed in string form in last
argument to mount(2)), such as "rootcontext" or "context" are in fact common to
all filesystems, including fuse. We should pass them down to the actual
mount(2) call untouched.

This is achieved by adding "fuse-mountopts" option to mount/fuse translator and
adjusting the mount helper to propagate it with unrecognized options as they
are encountered.

mount/fuse: add mount-option "enable-ino32" for the native client

2012-09-07T01:32:26+00:00

By default the GlusterFS-native client uses 64-bit inodes. Some 32-bit
applications can not handle these correctly. Introduce a client-side
mount option "enable-ino32" which causes the FUSE-client to squash the
64-bit inodes into a 32-bit value.
